The one I bought here in England continues to do well - this pic is from this year
I've looked at some of the main clematis specialists in England (they pretty much all now sell c.k. Amber) but so far I haven't found any who will mail to the US. Thorncroft used to mail outside the EU but no longer do. If I hear of anyone willing to send to the USA, either from the UK or from France, I'll add a post here, although I fear it may be very expensive.
